LEON RAPHAEL LECELLIER, OF VILLEDIEU, FRANCE.

PROTECTOR FOR ELECTRIC OR OTHER BELLS.

SPECIFICATION forming part of Letters Patent No. 518,613, dated April24, 1894. Application filed July 31, 1893. Serial No. 481,970- (Nomodel.) Patented in France April 7, 1891., No. 212,612.

T at whom itmay concern.-

Be it known that I, LEON RAPHAEL LEOEL- LIER, of the city of Villedieu,Manche, France, have invented a Protector for Electric or other Bells,(for which I have obtained Letters Patent in France for fifteen years,dated April 7, 1891, No. 212,612,) of which the following is a full,clear, and exact description.

My invention relates to a device specially designed for application toan electric or other entrance bell whereby to prevent within certainhours of the night the ringing of the bell by any person other than atenant of the house or flat. This device is preferably made portable andis adapted to be secured in any well known manner to ordinary belloperating mechanism.

The invention comprises a key having a push pin which is freeto slidethrough the barrelof the key and which after the key bit has lifted thetumblers of the device may be caused to pass through holes in asupplementary series of tumblers and thereupon to act upon any ordinarypush button for closing an electric circuit or operating a pneumatic orother bell for example.

My invention is illustrated in the accompanying drawings forming part ofthis specification Figure 1 of which represents an outside face view ofmy protector for electric and other bells. Fig. 2 is a horizontalsection showing the connection between the ordinary and supplementarytumblers. Fig.3 is a transverse vertical section of the protector withthe key inserted therein, and Fig. 4 is a similar view showing the keyturned half round. Fig. 5 is a back View of the protector. Fig. 6 is aseparate view of the key.

Fig. 7 shows a face and edge view of one of the supplementary tumblers.

In the tubular barrel a of the key is a push pin 1) which is free toslide and is provided with a knob c which works within the bow of thekey. A small spring may be inserted between the button and the bow ofthe key for drawing back the push pin within the barrel.

The protectoris used in connection with the key above described andcomprises a set of tumblers (1, similar to thoseused in ordinary locksto each of which is riveted by means of a pin e, one of a series ofadditional tumblers f preferably made of steel and each provided with ahole 9 adapted to give passage to the push pin 1) of the key, when theholes are brought into line by the action of the key bit on the tumblersd. In rear of said tumblers on the back of the lock. casing is fixed abridge piece 41 through a hole in which the pin 6 also passes so as topress on a contact spring j secured to the bridge piece so as on beingpushed inward to abut against the push button or other means foroperating the bell or alarm.

Although the arrangement described is moreespecially intended forelectric bells it may be applied to an ordinary bell-pull by modifyingthe part upon which the push pin acts, and I do not wish to limit myselfto the exact arrangement and form of tumblers or look mechanism shown,since any ordinary arrangement may be used.

I claim- The combination with an electric or other bell operatingdevice, of a protector provided with an auxiliary set of perforatedtumblers connected to the key operated tumblers and of a key having apush pin fitted in its barrel and adapted to slide through the aperturesin the auxiliary tumblers when the latter are brought to position by theaction of the key, and to act on the bell operating device as specified.

The foregoing specification of my protector for electric and other bellssigned by me this 15th day of July, 1893.
